Product Features

Part 1

What is the PC Expanion

󲼷

?

The PC Expanion is a unique networking device using WoIP(Windows over

IP) or LoIP(Linux over IP) networking standards. Users can share the

resources of the host PC system by connecting a PC Expanion terminal(s) to

it, providing the benefit of having several networked PCs. Users can connect

one or more PC Expanion terminals to one host PC directly using a LAN

adapter and cable or via the network using a switch/router.

Features

Cost Effective

Save up to 80% of hardware cost versus buying a Pentum4 or equivalent

PC; the PC Expanion gives any office or home the ability to expand any

existing host PC easily and affordably.

Compatibility

The PC Expanion will run Windows or Linux based applications on a host

PC; applications include Internet browsing, email, office suites, most

games and much more.

No Maintenance Required

Maintenance and upgrades only apply to the host PC. The PC Expanion

requires no hardware maintenance, only occasional software updates.

Small sleek design

Space saving design allows more room for your office or desk area.

Secure and Fast

Our proprietary Terminal Protocol allows for a fast and secure

environment using image caching and 128 bit encryption

*No noise output and low power consumption, quiet operations while saving energy costs.

󳃐

Depending on the performance of the host PC, an application’s

compatibility and operating speed can vary. Refer to NComputing’s

web site for more information.
